WASHINGTON (CNN) - Republican Sen. John McCain is slipping in polls in his home state of Arizona.

According to a new survey from the American Research Group, Sen. McCain had previously polled at 45% in February, and is now at 32 percent in July. His decline appears to be tied to the rise of former Tennessee Sen. Fred Thompson, who has not yet formally announced his candidacy for president.

Sen. Thompson received 15 percent of the votes among likely GOP voters in the new poll.

Although I'm not a Ron Paul supporter the question as to why Ron Paul, and all the other candidates, are not included in the poll is very valid...and very telling regarding CNN bias.

If you look at any of the Arizona news outlets you will find multiple mentions of Ron Paul. Many people seem to like what he has to offer, even though his supporter can come across as kooks.

Polls based on human sampling are, by nature, flawed anyway. 600 people polled out of, oh I don't know, 1,055,252 (2006) registered republican voters are used to quantify how Arizona will vote? Puh-leeeez.

Why does the media try to impose their candidates on the
public? When a poll only adds up to 84%, the real news story becomes, what happened to the other 16%? If my math is right 16% is more than the third place finisher's
15%. Does the media think the public cannot see that?

I wouldn't vote for any of these guys, or Ron Paul either, under any circumstances, but I agree with the posters above. CNN lists candidates getting only 7%, but says nothing about who got the missing 16%? Are you trying to influence, rather than just report, the news? And why aren't you responding to these questions?

The earlier comments about this poll have said pretty much that I wanted to say. One thing I may add is that if Ron Paul supporters come across as kooks, they will be easy to spot, especially as their ranks grow every the day.

Who had thought that Republican Party would be lucky enough to come up with a candidate like Ron Paul?
